EYELET.

SPECIFICATION forming part of Letters Patent No. 708,577, datedSeptember 9, 1902.

Application filed February 8, 1902. Serial No. 93,195. (No model.)

To all whom it' may concern:

Be it known that I, GEORGE E. MCCORMACK, a. citizen of the UnitedStates, residing in East Bridgewater, in the county of Plymouth andState of Massachusetts, have invented a certain new andusefullmprovement in Eyelets, of which the following is a specification.

This invention relates to eyelets made,pref erably, of sheet metal andof the class which are provided with setting flanges or heads, sucheyelets being used principally, but not necessarily exclusively, inconnection with leather boots and shoes; and the invention has for itsobject to provide an eyelet which while light in weight has a flangewhich is heavy in proportion to the band and very strong and stiff, sothat the band can easily spread under the pressure of the setting-toolswithout any yielding or deformation of or injury to the flange andwhereby the paint or enamel cannot easily crack olf from the flange.

My present invention comprises an eyelet the flange of which consists oftwo thicknesses or layers of metal, said thicknesses 'bein g foldedagainst each other, so that the under thickness is in actual contact forits entire width and length with the upper thickness, the twothicknesses or layers being concavoconvex in cross-section andconcentric and with their grooved or hollow portion facing downward andthe under layer being preferably thicker or heavier than the upperlayer, all as fully described below,and illustrated in the accompanyingdrawings, in Which- Figures I to 6, inclusive, are transverse verticalsections illustrating the different steps in the method by which myimproved eyelet is preferably constructed Vfrom the blank. Fig. 7 is asimilar section of the complete eyelet embodying my invention. In eachof these figures the eyelet is shown on an enlarged scale, Figs. l to 6,inclusive, showing it as on a scale about one-half the size of' thescale indicated in Fig. 7.

To form the eyelet, a cup, substantially as illustrated in Fig. l, ismade from a round blank, and from this cup the form illustrated in Fig.2 is constructed, the upper part of which shows the beginning ofaflange. This flange is then turned down into the shape indicated inFig. 3 and then inward into the shape indicated in Fig. 4, in which theflange comprises two thicknesses of the instal. The barrel is then drawnin slightly and the ange rolled, as shown in Fig. 5, and the barrel isthen pierced, as shown in Fig. 6. In Fig. 7 the device is complete andshows the barrel A tapered or growing thinner toward its lower end andwith its upper portion spreading into a flange,which consists of theupper layer or thickness B and the lower layer or thickness B. The lowerlayer is somewhat thicker than the upper layer, is in contact with itthroughout its entire length and Width, and the flange thus constructedis concave-convex in crosssection and with its concave or hollow sidefacing downward. This flange is not only relatively heavy as comparedwith the barrehbut is by reason of its shape exceedingly strong andstiff, so that the enamel or paint applied to the flange will not beindanger of cracking off. Moreover,when the eyelet is applied the flangeis reinforced or strengthened, for the reason that the leather, cloth,or other material in whichlthe eyelet is used fills up the groove orcavity under the flange. The barrel, especially the lower portion of it,is relatively thin, and hence can be easily spread under the pressure ofthe setting-toolls,while\ the thickness and stiffness of the flangeprevent its being forced out of shape.

While the method above described may be the preferable one, yet I do notdesire to confine myself to such method in all or any of its steps.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is#

The herein-described improved sheet-metal eyelet, comprising the barrelA, and the circular flange consisting of two thicknesses or layers ofmetal B, B', concentric in cross-section and in physical contact witheach other throughout their entire width and circumference or length,the peripheral portion B of naine to this specication in the presence ofthe metal constituting the flange bein g folded two subscribingWitnesses.

under the portion B, and eorrespondino in shape thereto, and the flangebeing formebd to GEORGE E' MCCORMACK' 5 produce an annular groove on itsunder sur- Witnesses:
